Technical scheme

 

1. Mast requirements
(1)★The height of the mast is 10m. The lifting process takes no more than 5 minutes. (This article cannot be deviated from)
(2)★Contraction height: no more than 2.2 m. (This article cannot be deviated from)
(3)★Rated load: not less than 150kg. (This article cannot be deviated from)
(4) installation method: internal installation
(5) maximum outer diameter: 228 mm
(6) tube wall thickness: average 4 mm
(7) casing type: mechanical pin locking with T-type handle
(8) wind resistance: Level 8 wind works normally, level 12 wind does not damage
(9) surface treatment: anodic oxide layer
(10) when the mast needs to carry the base station antenna, feeder and control device configured in this project, the vertical shaking amplitude should be less than ± 2.2 ° under the 8-level wind, the horizontal twist amplitude is less than ± 1.2 °.
(11) during the process of rising and falling, the mast can be locked at any position, and has a backup locking device, which can lock the mast when the power system fails.
(12) the mast has safety and backup measures. When the automatic lifting function fails, it can be manually lifted.
(13) the main part of the mast is made of high quality and high strength materials, and the surface is treated with anti-corrosion and waterproof of special materials. The corrosion failure period of the main body is more than ten years in harsh environment such as salt spray.
(14) the mast should have lightning protection system and good lightning protection capability to eliminate the threat of thunderstorm to equipment and people.

 

2. Mast configuration scheme
(1) use a mast to carry the original base station antenna, Feeder, etc.
(2) based on the antenna feeder, Lightning arrester and antenna feeder control device of this project, carry out load-bearing and vertical sloshing amplitude and horizontal twisting amplitude index accounting of the lifting tower under level 8 wind.
